Equipment Description

Transformer GDpack is designed and manufactured to accept oil or dry transformers.

Medium Voltage GDpack can be provided with different options of Medium Voltage 40.5kV Switchgear from our SF6 insulated compact secondary switchgear portfolio.

Low Voltage The LV compartment could accommodate an LV panel with ACB or MCCB’s and various number and ratings of outgoing feeders depending on transformer size and customer needs. Special low voltage equipment is available upon request.

Additional equipment• Devices for metering and control circuit • SCADA ready for easy connection to any SCADA System through standard

communication protocols.• Power Factor Correction Panel• Remote Terminal Unit (RTU) to monitor the CSS and store data for operation,

maintenance and fault analysis. Local and remote monitoring operations available.

Installation

• Factory delivers a factory tested solution to the installation site, and provides all necessary lifting device for moving the substation.

• No complicated civil engineering job is needed in advance or during the installation.• Only a pit has to be excavated and the substation has to be placed into this installation

pit.• When the substation is in its place, than the commissioning can be started after the

incoming and outgoing cables had been connected.• For detailed information please see our installation manual.
